You use a cold header to shape metal wire into strong parts. The cold heading process works at room temperature, so you do not need to heat the metal. This method helps you save time and energy. You can follow these steps to understand how the cold heading process works:
You feed a coil of metal wire into the cold header. The machine straightens the wire and cuts it into short pieces called slugs.
You position each slug in the die. The die holds the slug in place for shaping.
You use a punch to press the slug into the die. The punch deforms the metal and fills the die cavity. This step forms the basic shape of the part.
You may need several blows for complex shapes. Multi-stage cold heading helps you create detailed parts.
You eject the finished part from the die. The cold header pushes the part out quickly.
You repeat the cold heading process at high speed. Automation lets you produce thousands of parts every hour.
The cold heading process uses wire rods that have gone through spheroidizing annealing. This treatment makes the wire softer and easier to shape. You can form low and medium carbon steels without heating them. The cold heading process gives you strong parts with good mechanical properties.
Tip: You can combine forming, trimming, and threading in one cold heading process. This saves you time and reduces extra steps.
You find that the cold heading process helps you meet tight production schedules. You can adapt to market changes because you produce large quantities of parts quickly. The cold heading process supports efficient mass production and reduces waste.
You can use different cold heading techniques to create many shapes and sizes. Each technique gives you a way to form metal at room temperature. Here is a table that shows the most common cold heading techniques:
Technique Type | Description |
|---|---|
Cold Heading Upsetting | You force the metal out of the die with a punch to make a head larger than the blank. |
Cold Heading Extrusion | You use forward or reverse extrusion methods to shape the metal. |
Forward Extrusion | You feed a metal slug into the machine. Dies and punches shape it at room temperature. |
Open Extrusion | You deform a metal slug through a die with an open end for consistent shapes. |
Trapped Extrusion | You form parts by forcing a slug into a confined space in the die using a punch. |
Backward Extrusion | You make the metal flow in the opposite direction of the punch. This technique works well for fasteners. |
You can choose cold heading techniques based on the part you want to make. Cold heading upsetting helps you create bolts and screws with large heads. Cold heading extrusion lets you form long, thin shapes. Backward extrusion works best for hollow parts like rivets.
